The monkeys in India, knowing by instinct the malignity of the snakes, are most vigilant in their destruction; they seize them when asleep by the neck, and running to the nearest flat stone, grind down the head by a strong friction on the surface, frequently looking at it, and grinning at their progress. When convinced that the venomous fangs are destroyed, they toss the reptiles to their young ones to play with, and seem to rejoice in the destruction of their common enemy.
